In the world of technical analysis, traders are often conditioned to look for patterns that work. We hunt for the perfect setup, the textbook example, the high-probability trade. But what if there was an edge to be found in failure? What if the breakdown of a classic pattern could be just as profitable, if not more so, than its successful completion? This is the contrarian philosophy behind trading the failed ABCD pattern. For the experienced swing trader, learning to identify when an ABCD pattern is likely to fail, and knowing how to capitalize on that failure, can open up a whole new dimension of trading opportunities.

The Anatomy of a Failed ABCD Pattern

A failed ABCD pattern occurs when the price action does not follow the expected sequence of events. In a bullish ABCD pattern, this could mean that the CD leg fails to reach the AB=CD projection, or that the price breaks down through the C point. In a bearish ABCD pattern, the opposite would be true. The key to trading failed patterns is to understand the psychology behind them. A failed pattern represents a shift in market sentiment, a moment when the prevailing trend is not as strong as it appeared to be. This shift can create a effective and explosive move in the opposite direction.

Identifying the Signs of a Failing Pattern

There are several key signs that can alert you to the possibility of a failing ABCD pattern:

  • Lack of Momentum in the CD Leg: If the CD leg is choppy, overlapping, and struggling to make new highs (in a bullish pattern), it is a sign that the buying pressure is weak. A healthy CD leg should be a strong, impulsive move.
  • Volume Divergence: If the price is making new highs in the CD leg, but the volume is declining, this is a classic sign of divergence. It suggests that the move is not supported by strong conviction and is likely to fail.
  • Break of a Key Trendline: If the price breaks below a key trendline that has been supporting the advance, it is a strong indication that the trend is changing.
  • Failure to Hold the B-Point: A important test for a bullish ABCD pattern is the B-point. If the price rallies up to the B-point and is strongly rejected, it's a sign that sellers are in control.

Entry Rules for Trading the Failed Pattern

Your entry rules for trading a failed ABCD pattern will be the inverse of your rules for trading a successful pattern.

  • Entry on the Breakdown: The most common entry is to short a bullish ABCD pattern when the price breaks below a key support level, such as the C point or a key trendline. In a bearish ABCD pattern, you would look to buy when the price breaks above a key resistance level.
  • Confirmation of the Failure: Do not anticipate the failure. Wait for the pattern to confirm that it has failed. This means waiting for a clear break and close below the key support level.
  • The "Look and Go" Entry: A more aggressive entry technique is the "look and go." This involves entering the trade as soon as the price looks like it is going to break the key support level, without waiting for a close. This can result in a better entry price, but it also carries a higher risk of a false breakout.

Exit Rules for the Contrarian Trader

  • Initial Target at the A-Point: A logical first target for a failed bullish ABCD pattern is the A-point of the pattern. This is a natural area of support, and it is common for the price to bounce from this level.
  • Measured Move Targets: You can also use a measured move projection to set your profit target. For example, you could project the height of the AB leg down from the breakdown point.

Profit Targets in a Reversal Scenario

  • Exploiting the Surprise: Failed patterns can lead to very fast and effective moves, as they catch the majority of traders off guard. Be prepared for the possibility of a much larger move than you might initially expect.

Stop Loss Placement for the Counter-Trend Trade

  • Above the Breakdown Point: Your stop loss should be placed above the point where the pattern failed. For a bullish ABCD pattern that has failed, you would place your stop loss above the breakdown point (e.g., the C point).

Position Sizing for a Contrarian Play

  • Consider a Smaller Size: Trading against the prevailing trend can be a higher-risk strategy. It may be prudent to use a smaller position size than you would for a trend-following trade.

Risk Management for the Failed Pattern Trader

  • The Risk of Being Wrong: The biggest risk in trading failed patterns is that you are wrong, and the pattern ends up completing after all. This is why it is so important to wait for confirmation of the failure before entering the trade.

Trade Management in a Reversal

  • Aggressive Profit Taking: Because failed patterns can lead to very fast moves, it is often a good idea to be aggressive with your profit taking. Consider taking partial profits at your first target and then trailing your stop for the remainder of the position.

The Psychology of Trading Against the Crowd

  • The Courage to Be a Contrarian: Trading failed patterns requires a certain amount of courage. You are betting against the prevailing wisdom of the crowd. You must be confident in your analysis and be able to withstand the psychological pressure of going against the herd.
  • The Humility to Admit When You're Wrong: Just as with any trading strategy, you will not be right 100% of the time. There will be times when you call for a failed pattern, only to see it reverse and complete. You must have the humility to admit when you are wrong and to take your loss quickly.

Trading the failed ABCD pattern is a effective and profitable strategy, but it is not for the novice trader. It requires a deep understanding of market psychology, a keen eye for detail, and the courage to go against the crowd. By learning to identify and capitalize on the failure of this classic pattern, you can add a valuable and non-correlated strategy to your trading arsenal.
